To all whom it may concern:

Be it known that I, LEVI T. SNo-w, a citizen of the United States,residing at New Haven, in the county of New Haven .and StateefConnecticut, have invented va new and useful Improvement inSafety-Razors; and I do hereby declare the following, when takenin-connection with the aciiompanying drawings and the letters ofreference marked thereon, 'to be a'full, clear, and exact description ofthe same, and which said drawings constitute part of this specification,and re resent, inv igure 1 a view in front elevation of my improvedsafety razor. Fig. 2 a view thereof in central longitudinal -section.Fig. 3 a view thereof in transverse section on the line er -1b of Fig.2, drawn on an enlarged scale. *Fig. 4 a broken view of the razor inrear elevation with the pivotal operatingplate removed to expose thespring on which the razor-blade rests. Fig. 5 a detached view of therazor-blade. Fig. 6 a detached view in inside elevation of the pivotaloperatinglate. a

y invention relates to an improvement in safety razors, the object beingto produce a simp e and compact device constructed venience and in use.

With these consists in a safet razor having certain-details ofconstruction as will be hereinafter described and pointed outin theclaims.

In carrying out tmy invention-as herein shown, I em loy astraighttubular handle 2 formed Wit knurled bandsor fillets 3 to improve the griof. the hand upon it. At its upper end this handle is furnished with abacking-plate 4 extended in its axial line, concavo convex incross-section and formed alongits side edges with teeth '5 which makethe comb of the device; To the inner face of the backing-plate 4 Isecure a wide sheet? metal blade-supporting spring 6 upon which theremovable rigid razor-blade 7 isplaced so as to rest at points near itsends u on the square ends of the spring. The sai blade is mounted, as itwere, 111 a longitudinally movable and pivotal carrying oroperatingplate 8 also concavo convex in cross-section and narrower inwidth than the blade 7 which is narrower than the bod of thebacking-plate 4 or exclusive of t e combteeth 5 thereof. The blade 7 isreversible eflectiveness end foriend and formed at its ends with cor- Jends in" view my invention outer end of the upper end of the backioperating-plate 8 is responding notches 9. The outer notch 9, whicheverof the two it maybe, receives a positioning pin 10 located within aforwardly ent hook 11 at the outer end of the late 8, while at the sametime the other notch at the blade 7 ada ts it to .be fitted over apositioning pin 13 located near the lower end of the to a correspondinghoo end thereof. The hook forward through 14 nearer the lower 1 1aforesaid passes a wide notch 15 in the 'ng-plate 4 and engages with abevel 16 at the bottom of the said notch 15 which is also formed with acut 17 to clear the pin 10. a The said hook 14 passes forward through anopening 18 in the ower end of the backing-plate 4 for engagement with abevel 19 formed adjacent to the lower wall of the said opening. The saidoperating plate 8 is pivotallyattached at its lower end to a rod-likestem 20 the lower end of which is threaded for entrance into thethreaded hub 21 of a cylindrical rotatable finger-piece 22 the said hub21 of which is adapted to be entered into the lower end of the handle 2to which the fingenpiece 22 corresponds in.diameter. In effect thefingerp1ec e .22 is a part of the handle 2. with particular reference tosuperlor con- In uslng my device, the finger-piece22 is turned fromright to left to permit the operating-plate 8 to be drawn outward withrespectxto the backing-plate 4 so that the hooks 11-and 14 of the lattermay be disengaged from the bevels 16 and 19 of the former. The

nto Its open position inwhich the blade 7 is applied to it. The plate isnow swun back into itsclosed position whereby theb ade is engaged withthe ends of the spring 6 which is flattened by drawing the plates 4 and8 together between the :fingers so as to register the hooks 11 and 14with the notch 15 and opening 18 respectivel The finger-piece 21 is nowrotated from eft to right whereby the operating-plate is longitudinallydrawn inward and its hooks 11 and 14 brought into coaction with thebevels then draw the operating-plate laterally for ward toward thebacking-plate, whereby the blade is firmly held with its cutting edgesseparated from the comb-teeth 5 by a distance directly proportioned tothe flattening of the spring 6. The more the finger-piece 21 is turnedfrom left to right, the more the operating-plate will be .drawn inwardand forward and the more the spring 6 will be now free to swingdown 16and 19 which late 8 and adjacent plates being adapted to vention somechanges from the construction herein shown and described may be made. I

would therefore have it understood that I do not limit myself theretobut hold myself at liberty to make such departures therefrom as v fairlyfall within the splrit and scope of my invention.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent isz- I 1. In a safety razor, the combinationwith a handle, of an alined backing-plate. rigid therewith, anoperating-plate registered with the backing-plate and connected at itsouter end with the outer end thereof, the two have a double-edged razorblade introduced between them, and means connected with the saidoperatingplate for moving the same laterally with respect to thebacking-plate.

2. In a safety razor, the combination with a tubular handle, of analined backing-plate ri id therewith, an operating-plate registered wlththe backing-plate, the two plates being adapted to have a double edgedrazor blade introduced between them, means for moving theoperating-plate laterally with respect to the baclring-plate, and meanslocated within the tubular handle'for moving the operatingplatelongitudinally. I

3. In a safety razor, the combination with a handle, of an alinedbacking-plate rigid therewith, of an operating-plate registered with thesaid backlng-plate and formed upon its edges with guard-teeth, the twoplates being adapted to have a double edged razor blade introducedbetween them, and means combined with the said handle and coactingwiththe operatingplate for operating the latter.

4. In a safety razor, the combination with a handle, of an alinedbacking-plate rigid crating the therewith, an operatinglate registeredwith the said backing-plate, tihe two plates being adapted to have adouble edged razor-blade introduced :between them, a stem located in thesaid handle and pivotally connected with the operating-plate, meansmounted in the handle and connected with the stem for opoperating-plate,and means for coupling the ends of the two plates, whereby theoperating-plate is laterally moved with respect to the backing-platewhen the operatinglate is longitudinally moved.

5. n a safety razor the combination with the handle thereof, 0 abacking-plate ri id therewith and in line therewith, a stern located inthe said handle, an operating-plate pivoted to the said stem, means forconfinin a razor blade between the 'saidbacking and o erating plates,means for coupling the two p ates to ether, and a finger-piece combinedwith the andle and connected with the said stem for adjusting theoperating-plate longitudinally.

6. In a safety razor, the combination with the handle thereof, of abacking-plate rigid therewith and extended in the axial line thereof andformed upon its edges with .comb teeth, an operating-plate between whichand the backin -plate a razor-blade is confined, and means for adjustingthe operating-plate for setting the edges ofthe razor blade with respectto the teeth of the comb.

7 In a safety razor, the combination with the handle thereof, of abacking-plate extending in line with the said handle and rigid therewithand formed with two bevels, a comb, an operating-plate formed with hookscoacting with the said bevels,,and means for adjusting the saidoperatinglate longitudinally; whereby the said hoo rs are moved withrespect to the said bevels and the edges of the razor-blade positionedwith respect to the comb.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.
